Images taken with the Hyperstar and SXV-H9C Camera

Leo Trio a brighter version

The version below – but a little brighter :)

Looking at this image with fresh eyes this morning rather than towards midnight last night – it looked to dark overall, so brightened it up a bit.

Leo Trio Registar combined data

This is a composite image showing the Leo Trio region.  Hyperstar III data taken on 21st March 2010 has been combined with older Hyperstar 1/H9C (2-frames) data from much earlier.  The composite was created using the powerful registering program Registar.

Rosette final twiddles

Carried out some final (?) processing twiddles on the Rosette composite – think it’s just about there now :)

Handled the old data slightly differently in this Registar composite reprocess.

M45 original Hyperstar

Here is a 4-frame mosaic of the Pleiades taken with the original Hyperstar lens assembly (on a C11) with a tiny little H9C one-shot colour camera.  Also happens to be one of my all-time favourite images.

The Cave nebula in Cepheus

Another deep-sky image from the NFO archives, and another original Hyperstar/H9C composition.  This time the Cave nebula in Cepheus.  I recall the tracking was so good on this one that I actually got some vertical banding where the tracking error was well within 1-pixel for the whole imaging session.  Not sure why it was quite so good that time, something to do with where I was imaging in the sky as well as several other things all working together with me for a change, but I never managed to repeat the precision tracking with this system afterwards :(

M78 blast from the past

Another old image from the New Forest Observatory taken with the original Hyperstar and a little SXV H9C one-shot colour camera (1.4 megapixels only!).  The camera was highly sensitive and I regret selling it when I bought the APS-sized chip M25C.  This image of M78 was taken using just two hours of total imaging time showing the enormous speed (f#1.85) of the original Hyperstar.
